摘　　要：流线可视化是流场可视化的重要技术之一,提出了基于流函数与流体运动分解的流线构造模型,阐述了根据流函数与流体运动分解确定流体质点流出面的绘制原理,给出了根据流函数确定流体质点流出位置方法,推导出了不同情况下的离散点间的连接曲线,根据文中流线构造模型开发了流线绘制程序,绘图实例能够比较准确地反映流场的局部细节。Streamline visualization is an important technique for flow field visualization. The streamline visualization model based on the streamline function and the fluid flow velocity decomposition was put forward. The protract theory to identify the outflow surface of fluid flow based on the streamline function and the fluid flow velocity decomposition was elaborated. The method to gain the position of the outflow surface of fluid flow based on the streamline function was given, The connection curves between two points for various conditions were derived, The strea^niine protract program based on my streamline visualization model was developed. The location conditions of flow field in the protract example are accurately shown.
